Challenge Problems

Push your limits with challenges.

Question 1

Design a CE amplifier circuit. If the components are R1 = 1kΩ, C1 = 100nF, and the gain is required to be 10, derive the transfer function and identify the poles.

💡 Hint: Focus on summing the effective resistances and capacitances in the circuit.

Question 2

Given a CS amplifier with load capacitance C2 = 33pF and a target low cutoff frequency of f = 1kHz, calculate the required input capacitance.

💡 Hint: Use the frequency cut-off formula to relate R and C, focusing on the characteristics of capacitive loads.
